What was Isaac Newton like? Secretive, vindictive, withdrawn, obsessive, and oh, yes, brilliant. His imagination was so large that, just “by thinking on it”, he invented calculus and figured out the scientific explanation of gravity. Yet Newton was so small-minded that he set out to destroy other scientists who dared question his findings. This compelling portrait of Newton, contradictions and all, places him against the backdrop of 17th-century England, a time of plague, the Great Fire of London, and two revolutions.

Nos preparamos en casa para enfrentarnos a desastres naturales y emergencias climáticas. Si se acercan vientos fuertes, inundaciones y tormentas de nieve podemos quedarnos (resistir) o irnos (evacuar). ¿Pero qué pasas cuando los zoológicos, acuarios o santuarios están en el camino de la tormenta? ¿Cómo se prepara el personal del zoológico para proteger a los animales? ¿Quién puede ir a ayudarles?

Al igual que las familias de los humanos, las familias de los animales tienen diferentes formas y tamaños. Muchos padres animales en la naturaleza tienen roles inusuales y generosos en la crianza de sus hijos. Mientras que algunos padres animales puede que nunca conozcan a sus descendientes, hay algunos que protegen y dan cobijo a sus pequeños. Otros alimentan o enseñan a sus hijos. Aprendamos más sobre cada uno de estos padres salvajes y sus tareas esenciales.

Al igual que los humanos, los delfines aprenden jugando, observando y experimentando. Algunos comportamientos aprendidos son cosas divertidas para pasar el tiempo. En diferentes partes del mundo los delfines han aprendido algunas técnicas de caza fascinantes. Sin importar si el comportamiento aprendido es enseñado de generación en generación o aprendido mediante la observación, esos delfines tienen habilidades de caza únicas que solo pueden encontrarse en esas zonas.

Marine mammals known as cetaceans are broken into two large groups: toothed whales (including dolphins and porpoises) and baleen whales. One group has a single blowhole to breathe air, the other has two. One group has tall dorsal fins to help maintain balance as they chase prey. The other scoops up water and prey in their large mouths as they swim slowly along—they don’t need large dorsal fins. One group uses echolocation, the other doesn’t. Learn more about what these animals have in common and how they are different in this latest installment of the Compare and Contrast Series.

We prepare at home for natural disasters and weather emergencies. If high winds, floods, and snowstorms are heading our way, we can stay (ride it out) or leave (evacuate). But what happens when zoos, aquariums, or sanctuaries are in the storm’s path? How do zoo staff plan to protect the animals? Who can come to help them after the storm has passed?

Just like human families, animal families come in all shapes and sizes. Many fathers in the wild have unusual and unselfish roles in the rearing of their offspring. While some animal fathers may never meet or know their offspring, there are some that protect and shelter their children. Others feed or teach their young. Let’s learn more about each of these Wild Fathers and their important duties.
